Curate, connect, and discover
Miles Edgeworth is both extremely perceptive about other people’s intentions and motivations, but also terrible at understanding how his own actions affect others. It’s quite an interesting nuance that I think is often overlooked.
When Edgeworth returns in 2-4, he is already aware of what Phoenix is lacking as an attorney before he even knows the full extent of Phoenix's crisis (Maya being kidnapped). In their first conversation, Edgeworth says: "In order to understand this case, you have to understand a certain "truth"". He knows that Phoenix's current motivation for being a defense attorney is flawed (cue his "we are not heroes" line). However, at the same time Edgeworth doesn’t fully understand how his actions of disappearing have affected both Phoenix and Franziska.
Another very obvious example of this is in AAI (I think?). In response to Kay asking: “Have you guys not decided if you are going out, or is it just one sided?” Edgeworth says: “‘Decided’…? Shouldn’t the parties involved naturally just know…?” Edgeworth thinks people in a relationship should instinctively perceive the feelings of the other person without communicating. He doesn’t consider the possibilities of misinterpretation or misunderstanding.
So in the context of Wrightworth, essentially what I'm saying is that unless something like fear is holding him back, Miles definitely knows about Phoenix's feelings. It's Phoenix who's off somewhere deluding himself.
